Abstract: The device for attaching an artificial tail to an animal is a device for securing an upper portion of an artificial animal tail to a portion of the animal's natural tail. The device includes a longitudinally extending strap and a laterally extending strap, with the longitudinally extending strap being joined to the laterally extending strap adjacent respective first ends thereof. The laterally extending strap is positioned orthogonal to the longitudinally extending strap. In use, the longitudinally extending strap extends in the horizontal direction, and the laterally extending strap extends in the vertical direction. The longitudinally extending strap is looped around the upper portion of the artificial tail and a portion of the animal's natural tail, and the laterally extending strap is similarly looped around the artificial tail and a portion of the animal's natural tail to secure the artificial tail to the natural tail in both lateral and longitudinal directions.
